Description

一种便于更换蓄电池的电动汽车电池箱
技术领域
本发明属于电动汽车技术领域，具体涉及一种便于更换蓄电池的电动汽车电池箱。
背景技术
汽车工业发展带来的石油资源短缺、环境污染、交通事故等问题日益突出，电动汽车因其在节能、环保和性能方面具有传统汽车无法比拟的优势，已成为未来汽车工业发展的方向。电动汽车的能量供给主要有整车充电和电池更换两种方式。采用电池更换方式可大幅减少电动汽车的电能补给时间，同时有利于提高动力电池利用效率及使用寿命，正受到越来越多的关注。但是，电动汽车蓄电池体积大、质量重、数目多，使得蓄电池更换过程繁琐，既耗时又费力。蓄电池上有正负极接线孔用于电线的连接，多个蓄电池放在电池箱中时，电线就会比较多，当更换蓄电池时，需要把每根电线进行断开，这个工序就比较复杂。蓄电池在更换时，正负极电线的断开顺序也是有讲究的，首先断开负极，再断开正极，因为汽车都是负级搭铁,负级搭铁可以防止电磁干扰。在车辆维修中需要断电时只要把电瓶负级拆下,就不易造成短路。综上所述，目前的电池箱中并不满足对于蓄电池进行快速更换的要求。
发明内容
本发明意在提供一种便于更换蓄电池的电动汽车电池箱，以解决目前的电池箱中，蓄电池更换起来费时费力的问题。
本方案中的一种便于更换蓄电池的电动汽车电池箱，包括箱体，所述箱体内设有设有若干个放置蓄电池的凹槽，所述箱体的侧壁上设有用于连接蓄电池正负极接线孔的接线机构，所述接线机构包括接线柱和操作螺栓，所述接线柱水平穿设于箱体的侧壁上，接线柱上设有接线槽和卡圈，所述卡圈与箱体侧壁之间安装有弹簧，所述卡圈和弹簧位于箱体侧壁的内部，所述接线柱的前端朝向放置蓄电池的方向，接线柱的前端设有接线丝，所述接线丝穿过接线柱的内部连接于接线槽，所述接线柱的后端位于箱体侧壁的内部，所述接线柱的后端为圆锥状或半球状，所述操作螺栓竖直穿设于箱体侧壁的上侧，所述操作螺栓与箱体侧壁螺纹连接，所述操作螺栓的下端为圆锥状或半球状，所述操作螺栓的下端对准接线柱的后端，所述操作螺栓向下移动推动接线柱水平移动。
本发明的工作原理和有益效果：
本发明在操作时，先将蓄电池放入凹槽中进行固定，放置其在电池箱中晃动，并且蓄电池上的正负极接线孔要朝向设有接线机构的一侧。然后用手旋转操作螺栓，控制操作螺栓向下移动，由于操作螺栓的下端为圆锥状或半球状，接线柱的后端为圆锥状或半球状，当操作螺栓的下端与接线柱的后端接触时，操作螺栓向下的力会让接线柱的后端产生水平方向的分力，促使接线柱在箱体的侧壁水平移动，此时弹簧缩短。而接线柱水平移动，就会促使其前端伸入到蓄电池上的正负极接线孔中，接线柱前端有接线丝，接线丝穿过接线柱的内部连接于接线槽，因此预先将电线连接在接线槽中时，就能让蓄电池、接线丝、电线形成连通的电路，达到通电的效果，并且所有的电线都放置于箱体的侧壁内，不会显露在外面，让电池箱内非常整洁。
当需要拆卸蓄电池时，通过旋转操作螺栓，使其向上移动，当操作螺栓和接线柱分离时，弹簧伸长，接线柱在弹力的作用下，就会发生水平移动，接线柱的前端就脱离出正负极接线孔，使电路断开，并且卡环能卡住接线柱，防止接线柱完全滑入箱体侧壁内，此时就能进行取出蓄电池了。
使用本发明的电池箱，在安装和拆卸蓄电池时，只需旋转操作螺栓即可实现电线快速的连接和断开，非常的简单实用，相关的电线全都安放在电池箱的侧壁中，更加的安全，电池箱内也更整洁。
进一步，所述箱体内设有两排凹槽，两排凹槽之间设有隔断板，设置两排凹槽能让箱体在有限的空间放置更多的蓄电池，空间利用率更高，隔断板起到固定和隔开的作用。
进一步，所述隔断板上设有风机，风机可对蓄电池进行降温。
进一步，所述接线丝为铜丝，铜丝是廉价易得的材料，作为接线丝最为适宜。
进一步，所述操作螺栓的上端包覆有塑料层，因为操作螺栓是金属，用手操作起来比较困难，塑料层比较柔软，操作起来更舒服。
进一步，所述塑料层上设有螺纹，塑料层上设置螺纹，可以增大摩擦力，旋转时能拿得更稳。
进一步，所述操作螺栓的上端设有正负极标志，这样在安装和拆卸时，就能一目了然的知道正在操作的是正极还是负极了，非常方便。
附图说明
图1为本发明一种便于更换蓄电池的电动汽车电池箱的整体结构示意图；
图2为本发明中接线机构的结构示意图。
具体实施方式
下面通过具体实施方式对本发明作进一步详细的说明：
说明书附图中的附图标记包括：箱体1、蓄电池2、隔断板3、风机4、操作螺栓5、接线柱6、接线孔7、铜丝8、卡环9、卡圈10、弹簧11、接线槽12、塑料层13。
本发明提供了一种便于更换蓄电池2的电动汽车电池箱，包括箱体1，箱体1内设有设有若干个放置蓄电池2的凹槽，凹槽分为两排，两排凹槽之间设有隔断板3，隔断板3上设有风机4。箱体1的侧壁为中空结构，箱体1的侧壁上设有用于连接蓄电池2正负极接线孔7的接线机构，接线机构包括接线柱6和操作螺栓5，接线柱6水平穿设于箱体1的侧壁上，接线柱6上设有接线槽12、卡圈10和卡环9，卡圈10与箱体1侧壁之间安装有弹簧11，卡圈10和弹簧11位于箱体1侧壁的内部，所述卡环9位于箱体1侧壁的外部，接线柱6的前端朝向放置蓄电池2的方向，接线柱6的前端设有铜丝8，铜丝8穿过接线柱6的内部连接于接线槽12，接线柱6的后端位于箱体1侧壁的内部，接线柱6的后端为圆锥状或半球状，本实施例为半球状。操作螺栓5竖直穿设于箱体1侧壁的上侧，操作螺栓5与箱体1侧壁螺纹连接，操作螺栓5的下端为圆锥状或半球状，本实施例为半球状。操作螺栓5的下端对准接线柱6的后端，所述操作螺栓5向下移动推动接线柱6水平移动，操作螺栓5的上端包覆有塑料层13，塑料层13上设有螺纹，操作螺栓5的上端还设有正负极标志。
本发明在具体实施时，先将蓄电池2放入凹槽中进行固定，蓄电池2上的正负极接线孔7要朝向设有接线机构的一侧，然后用手旋转操作螺栓5，控制操作螺栓5向下移动。当操作螺栓5的下端与接线柱6的后端接触时，操作螺栓5向下的力会让接线柱6的后端产生水平的分力，促使接线柱6在箱体1的侧壁水平移动，此时弹簧11缩短。而接线柱6水平移动，就会促使其前端伸入到蓄电池2上的正负极接线孔7中。接线柱6前端有铜丝8，铜丝8穿过接线柱6的内部连接于接线槽12，因此预先将电线连接在接线槽12中时，就能让蓄电池2、铜丝8、电线形成连通的电路，达到通电的效果，并且所有的电线都放置于箱体1的侧壁内。
当需要拆卸蓄电池2时，通过旋转操作螺栓5，使其向上移动，当操作螺栓5和接线柱6分离时，弹簧11伸长，接线柱6在弹力的作用下，就会发生水平移动，接线柱6的前端就脱离出正负极接线孔7，使电路断开，并且卡环9能卡住接线柱6，避免其滑出箱体1侧壁，此时就能进行取出蓄电池了。
